Abstract: ABSTRACT OF THE DISCLOSURE         An x-ray tube anode target surface is provided with a coating for enhancing thermal emittance of the target.  To provide the coating, a mixture of fine particles is deposited to coat the target surface.  The mixture is then heated at a pressure of 10-5 Torr or lower and at a temperature in the range of 1650°C to 1900°C.  The mixture includes from about 2.5% up to about 20% by weight of TiO2, and from 70% to 93.5% by weight of at least one oxide selected from a first group consisting of ZrO2, HfO, MgO, CeO2, La2O3 and SrO.  To stabilize the oxide selected from the first group, the remainder of the mixture is at least one oxide selected from a second group consisting of CaO and Y2O3.

Abstract: WIRING ACCESS SYSTEM FOR DESKS          AND THE LIKE ABSTRACT OF THE DISCLOSURE The specification discloses a wiring system for desks, tables and the like in which an end edge trim piece located at the juncture between the top and side of the desk is releasably fastened thereto and can be removed to expose a relatively large aperture extending from the interior to the exterior of the desk to allow one to readily feed wiring therethrough.  The edge trim piece itself includes a relatively smaller opening which can then be positioned over the wiring when the end edge trim piece is resecured to the desk, the smaller opening being less noticeable than the larger opening would be.  The smaller opening in the trim piece includes a removable insert which can be oriented in different positions to provide yet further adjustment for the size of the opening through which wiring passes as it extends through the end trim piece.

Abstract: PAVANO 3.0-001 METHOD AND KIT APPARATUS FOR MAKING O-RINGS                    Inventor:  Robert J. Pavano ABSTRACT OF THE DISCLOSURE             A kit for making O-rings from cord stock material essentially includes a holding fixture for securing the material, a container of bonding liquid and a heating mold.  The holding fixture allows the cord material to be cut diagonally in such a fashion that the magnitude of the angle is smaller for cord materials having a smaller diameter.  Therefore, there is a larger bonding surface for smaller diameter materials.  The O-ring heating mold includes two flat separable heat condutive blocks having a common flat interface.  Apertures are located across the interface having cross-sectional diameters that are slightly less than the tube stock cross-sectional diameters.  Since the central axis of each aperture is not located directly at the interface one portion will include more than 180° of arc whereas the other portion will correspondingly include less than 180°.  With this structure it is possible to mate the two O-ring pieces in the heating mold where they will stay relatively immobile until locked in position by a locking screw.  A heating control mechanism is associated with heating element in the heat mold.  The kit can be employed to create custom sized O-rings in a relatively short period of time.

Abstract: SHARED DIRECT MEMORY ACCESS CONTROLLER                   ABSTRACT OF THE DISCLOSURE    A microprocessor system includes a microprocessor, a memory, and one or more direct memory access controllers, all connected to a common system bus which includes a system address bus and a system data bus.  At least one of the direct memory access controllers is shared by a plurality of sub-system device controllers which may control peripheral devices having diverse characteristics.  The microprocessor is limited in its instruction repertoire and may control peripheral de-vices only by means of an input and an output instruction.          The shared direct memory access controller includes no cir-cuitry which is specifically for controlling only a single type of peripheral device, the device dependent logic being located in subsystem device controllers.  Data transfers may take place directly between the memory and, through the shared direct memory access controller, any selected one of the peripheral devices.  In order to set up the actual data transfer, the microprocessor executes an Input instruction which addresses the status register in a selected subsystem device controller and returns this status to the micropro-cessor.  Next, two Output instructions are executed to load a memory starting address into an address pointer counter in the shared direct memory access controller.  Finally, an Output instruction is executed to address a control register in the selected subsystem device controller to load it with a command.  After this last operation the actual data transfer takes place on a byte basis through the shared direct memory access controller between the memory and the selected sub-system device controller.  The shared direct memory access controller includes an interrupt priority encoder and circuits responsive to an interrupt that is granted priority for placing the status and address of the interrupting subsystem device controller on the system bus.  Circuits are included in the shared direct memory access controller for "handshaking" between it and the memory, and between it and the subsystem device controllers.
